<span>y2(-2x + 3x2 + -8) = 0 if you're talking about factoring out the greatest common factor

The commutative property of addition states that a + b = b + a, in other words, the numbers in an addition problem can be flipped, but the result will be the same, the answer is C.
They are equal the 0 one the end of 0.60 doesnt mean anything
Answer:
0.9127
Step-by-step explanation:
We solve using this z score formula
z = (x-μ)/√n
where x is the raw score
We are told that:
The sample mean would differ from the population mean by less than 231 miles
μ is the population mean = 49360
Hence,
(x-μ) = 231 Miles
σ is the population standard deviation.
We were given variance = 6,568,969
Standard deviation = √variance
= √6,568,969
= 2563
n = random number of tires = 247 tires
z = 231/256/√247
z = 1.41648
Probability value from Z-Table:
P(x < 49591) = 0.92168
≈ 0.9217
The probability that the sample mean would differ from the population mean by less than 231 miles in a sample of 247 tires if the manager is correct is 0.9127
